- l VEHICLE-LAMP.

To all whom it mail concern:

. Be it known that I, ALBERT L. Annnnniie, a citizen of theUnited States, residing at Ghicago, in thejcounty of Cookand State of Illinois, have invented aqcertain new and useful Improvement in vehicle-Lamps of which the following-is a specification.

.My invention relates to vehicle lamps and is especially applicable to that typeof lamp commonly supported .1 within reach of the driver andmovably mounted in such mannor that the beam of ligl'it can be sent in various directions to illuminate particular parts oftheroadway. Lamps of this character are frequently called-Ssearch lights and spot lights. These lamps are commonly mounted justoutside of the vehicle body or top and consequently are not hidden either from the front or rear. The underlying object of my invention is to provide a lamp of this character which may be used to throw a powerful beam of light forward in driving and both forward and backward when the vehicle is standing still or parked. In the best form, the rearward beam has a red lens within its path, thus showing a red light at the rear. By preference, this red lens is a condensing lens, and by its use the rays will be confined within the desired angle, to warn drivers approaching from the rear.

I accomplish my objects by the mechan ism illustrated in the accompanying drawings in which,

Figure lis a side sectional elevation of the assembled device, and

fig. 2 is a front elevation showing part of the front glass broken away to reveal the parts behind it. I

Like numerals denote like parts throughout the several Views.

In the particular form selected to illustrate the invention, the main lamp bulb l is adapted to be inserted into a socket or receptacle 2 which, by preference, is located at the axis of a parabolic or other reflector 3. According to the best practice, the front of the reflector is closed by a plate ofglass 5. A bezel 6 holds therefiector and glass to the body or housing 7 of the lamp. The lamp body may, of course, assume various shapes and designs and may be supported in various ways. As spot lights and search lights for vehicles are well known, a description of the means for supporting the lamp body is unnecessary.

Y1 Specification of Letters Patent.

7 Application filed January 8. 1920. Serial No. 350,072.

An auxiliary lamp bulb 10 'is adapted to be supported in a socket or receptacle 12 mounted upon the bottom of the lamp body. The bulb and receptacle. are so po= sitioned and proportioned that the bulb comes within an opening 1 1- formed in the reflector. fThis opening ,is located prefer ably about half way between the bottom and I In any event,

the center of the reflector. the construction is such that when the auxiliary bulb 10 is in place andlighted,it will cast rays both forward from the reflector and rearward through an opening 15 in the lamp body. In the best form, a lens is mounted in the. opening 15 and, if the lens isof the condensing type, the rearward rays are concentrated and directed straight back ward where they may be seen by vehicles approaching from behind. By preference, the lens 16 is red the manner of a tail li 1t.

Vhile not essential, it is desirable to 1 with the result that a powerful beam of light is sent forward and a flood of light is thrown on any desired portion of the road.

The auxiliary lamp is left unlighted, ordinarily, the reason being that moving vehicles are commonly required to have independent tail lights for night driving. When the driver has reached his destination and wishes to leave the vehicle at the curb or to park it, he turns out the light from the main bulb and turns on thelight in the auxiliary bulb. When this is done, the light from the auxiliary bulb is thrown. partly forward and partly backward, the forward rays either passing directly through the glass front 5 or impinging upon the front surface of the reflector and being cast in a forward direction. This gives an abundant amount of light at the front of the lamp for parking purposes and serves as abundant warning to any driver approaching from the front. The rays passing rearward pass through the lens 16, thus creating a rearward projecting beam of light which, as above stated, is preferably colored red and condensed by the lens so as to form abundant Warning to adriver approaching from the rear. 7

= The sizes of the two bulbs may, of course,

be varied to suit the desires of the vehicle wner,b ut I have, found that a two or three candle power lamp is ordinarily quite sufli cient for the auxiliary light. WVhen the auxiliary'light is on, it is unnecessary to keep the taillight and the front lamps of thevehicle illuminated, for a lamp embodye ing this invention, is higher from the ground and out nearer the center of'the road, especially whein the device is mounted on the left side of-the-Vehicle isthemost'common practice-today. 1 it" will thus be observed that mydevicecombines within itself the characteristics of a headlight or search light .whendriving' andfa combined headlight and tail light when parking. It promotes'economy for it enables asingle small power lamp to furnishthe illumination for will be greatly appreciated by drivers who realize the calls made upon the battery of an ordinary motor vehicle.

Havingthus described my invention what I claim as new and desire to secure by Letters Patent, is:

A vehicle lamp having a casing provided with a substantially parabolic reflector adapted to throw the light rays forward, the reflector having means for supporting the main lamp bulb approximately at the axis of the reflector with the filament approximately at the focus of the reflector, the reflector also having an opening noncontrallylocated, all-auxiliary lamp placed in juxtaposition to said opening whereby the rays may be projected both forward and backward, the casing also having an opening in the back, and a transparent body extending across the opening inthe casing sul stantially directly back of the auxiliary lamp.

'In'wit'ness whereof, I have hereunto subscribed my name. I

ALBERT L. ARENBERG.
